The Fine aggregates are widely used in concrete and mortar. Use of fine aggregates in the concretes results in mining of riverbeds for aggregates. Excessive mining on the river bed causes environmental hazards and has the potential to change the hydrology of the region. It results in changing the natural drainage area of any watershed. It results in excessive cutting of riverbanks and also results in floods, landslides and river bank erosion. Further there is lot of generation of demolition waste as a result of development. Dumping of demolition waste in landfill is another environmental hazard which is again a cause of concern. Use of recycled aggregates as a replacement for river sand aggregate can solve the problem of mining and also of waste disposal. This paper compares the various properties of concrete made from fine aggregates from river sand and from demolition waste. There is reduction in workability and compressive strength due to increased porosity and non-uniform size of fine aggregate. The fineness modulus of recycled aggregate is higher than fineness modulus of river sand aggregate. All the power requirement for the test were met by generating power by 5 KW solar smart generation capacity. It uses hybrid inverter which directly supplies generated electricity during day time. The inverter uses r-MPPT technology which monitors output and can take power from panels, battery or grid and achieves optimization.
